The monitoring of antigen levels during inactivated poliovirus vaccine production: evaluation of filtration techniques.
The use of ELISA to estimate poliovirus antigen concentration has permitted an evaluation of the methodology used in vaccine production and allowed exploration of less wasteful filtration-techniques. The replacement of Seitz-EKS-1B filtration with either Seitz-Supra-EKS or Pall-filtration in the preparation of the vaccine could make a large saving in the total antigen yield, but the results in the safety test excluded their possible use in our process as it stands at the moment.
